No audio for Sony Alpha A7S XAVC S in DaVinci Resolve 11 lite?
“Hi, there, I’m running into a trouble that DaVinci Resolve 11 lite won’t recognize the audio from my Sony Alpha A7S XAVC S footage. The Sony A7s records in XAVC-S mode using LPCM 2-Channel (48 kHz 16 bit) audio. Does anyone have the same problem? It’s very disappointing. Hoping for a helpful solution. Please help.”
It’s probably because DaVinci Resolve and many other editing programs can only handle 48kHz PCM audio, like WAV files. Not LPCM audio. To be able to solve no audio issue between Sony Alpha A7S XAVC S and DaVinci Resolve, we would recommend converting Sony A7S XAVC S MP4 files to a format that is fully compatible with Resolve, such as Apple ProRes or DNxHD encoded MOV format, which DaVinci Resolve will recognize and handle well. This requires third party software like HD Video Converter.
You can download a demo version (for both, PC and Mac) to have a try.
This converter is easy to use and supports many different formats. Picture quality is very good for HD conversions. It will do what you want at a reasonable price.
